Oracles

Introduction

The Silo Protocol relies on external sources to determine the price of token assets listed in the protocol. Only governance can set price oracles for our markets. For example, SIP-25 was a proposal that the SiloDAO voted on to use Chainlink price feed instead of Uniswap V3 oracle to read the price of cbETH.
By having governance setting price feeds instead of multi-sig wallets, our silos remain resistant to tampering.

Tracking silos

We have worked with the Apostro team to develop a beta dashboard that tracks the health of our markets. You can access the tool on the following link:
Using the tool, you can track the following information:

Cost of oracle manipulation

  • N/A means the base asset in the silo, cbETH for example, doesn't use Uniswap V3 oracle.
  • Pump Cost: How much it would cost an attacker to pump the price of the base asset to max in over one block. For example, the cost of pumping WBTC price is estimated at $303M.
  • Dump cost means how much it would cost in dollar value to bring down the price of a token asset. For example, you can bring down the price of WBTC roughly by 50% but it would cost you $644M.

Attacks on Uniswap V3 oracles are reported under Alerts.
